Xerox 510dp Finisher Trouble

Working at an engineering company, I use ANSI standard sizes for
printing. Our finisher, which is lovely and folds these drawings for
me, has some trouble with the largest size documents that I use; ANSI
E, 34" x 44". If it does not fold correctly, one of two things
happens.

1.) A sheet will get caught halfway across the bridge and cause a
pile-up at the fuser exit. The printer or finisher generally notices
after 2 sheets are jammed between the fuser exit and the bridge.

2.) The other is a bit more insidious, as the printer/finisher never
notice when this happens. A sheet will come out at the fuser, with a
second that follows so closely they overlap briefly. The first enters
the finisher and folds normally. The second is spat onto the bridge,
unfolded. This continues in pairs until the job is complete, with nary
a chirp, squawk, beep or burble from either the printer or the
finisher.

Ideas on how to correct either or both of these? My technical guys
have looked at it, seen it happen, but sort of shrug and say, "We'll
look into it." In any given print job, I'm using half again as much
paper as I need, and I'd like to see this stop.

Thanks for your help; please let me know if you need further
information from me or if there is somewhere more appropriate to post
this.

 

This is an easy fix
1.Your field rep has a gap tool to measure for proper gap spacing
across the bridge at five points, each corner and the center. If the
bridge is not level or the rotation belts bind. The rotation clutch
fails to engage and a rotation jam occurs. Software is not fast enough
to respond to the error and hence the jam. This has been an ongoing
problem from at least 1999, when the finishers were built in italy.
